GUIDE-WHEEL AND GUIDE.

SPECIFICATION formingpart of Letters Patent No. 720,454, dated February 10, 1903.

Application filed March 26, 1900. Serial No- 10,Z87. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER H. MATHE- sIUs, acitizen of the United States, residing in the city of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Guide-Wheels and Details Connected Therewith, of which the following is a specification.

My invention has relation to means for conveying power from an electrical conductor, moving rope, or the like and also relates to certain details and apparatus to be used in connection therewith.

This application relates in part to improvements in guide-wheels, and comprehends certain modifications of improvements upon the general construction set out in Lett-ersPatout No. 432,757, granted to me on July 22, 1890.

In my Letters Patent above referred to I have disclosed an original type of guide-wheel having for its special novelty the divided center-bearing, which is made of a number of separate circular sections in a manner that each section is free to revolve with avelocity in correspondence to the length of its radius, thereby reducing the slipping and abrasion of the guide, rope, or the like and the centerbearing of the guide-wheel.

My present invention has for its object a further development of the same general featuresnamely, reducing the slipping and abrasion of'the contact-lines of the wire, rope, or the like and of the guide-wheel.

In carrying out my invention I make the center-bearing of the guide-wheel in one section, but narrower than the diameter of the rope, wire, or the like with which it is moving in contact for the purpose of reducing the difference of the different diameters of which the curved circumference of the center-bearing is composed, thereby simplifying the construction of the guide-wheel and making it more practical for general use.

In one form of my invention of the guidewheel I employ an independently-revolving center-bearing, which-has for its object to prevent the slipping and abrasion of the metals of the contact-lines, the flanges, and the sides of the rope, wire, or the like. The independently-revolving center-bearing of the guide-wheel has also for its object to reduce duced-inertia the independently-revolving center-bearing will start to revolve first around the hub or separating-ring upon .which it is journaled, and then gradually the rest of the guide-wheel will commence to revolve. Therefore a guide-wheel fitted with an independently-revolving center-bearing will revolve with less contact pressure and will cause less wear of the contact-lines than a guide-wheel with a fixed center-bearing. When guide-wheels are fitted with independently-revolving center-bearings and are applied to different classes of work and different sizes of rope, difierent designs are required for their details. I have shown two illustrations of these different designs in the drawingsone design for a small guide-Wheel incontact with a round wire and one design for a larger guide-wheel in contact with an angular wire. -In both of these guide-wheels the principle which governs the design of the center-bearing is practically the same; but the designs of the details of the rest of the guide-wheel are governed by different principles, which will be explained farther on.

In another form of the invention of the guide-wheel I make the center-bearing move as an integral part of the rest of the wheel.

- It may be made of one piece, as the ordinary guide-Wheel, except the center-bearing being made narrower than the diameter of the rope, wire, or the like, or it may be made with a detachable center bearing, which may be fastened to the wheel in any'suitable manner.

My invention embraces all center-bearings which are made narrower .than the round rope, wire, or the like with which they are brought in contact.

In the smaller forms of my invention of the sectional guide-wheel the flanges are shown in the drawings to be restrained on the bushing by screw-nuts, which are tightened or loosened by suitable wrenches, which are also shown in the drawings.

Myimprovements will be better understood by reference to the accompanying drawings, in which- Figure 1 is a side view of aguide-wheel fitted with an independently-revolving centerbearing designed for asmall round rope, wire, or the like.

Similarreference-numbersdenotelike parts throughout the various views of the drawings.

The bushing 1 (shown in Figs. 1, 2 and 7, S) is made of suitable material and of a shape and size to be forced into the hub 2, which holds it in place by friction. The bushing is also provided with a central longitudinal hole for receiving a pin or axis around which the bushing, and with it the guidewhee1, may revolve.

The hub 2 (shown in Figs. 1, 2 and 11, 12) is made of suitable material and is provided with a central longitudinal hole to receive the bushing 1. The hub 2 is also provided near one end with a shoulder 2 and at the other end with screw-threads 2, adapted to receive the screw-nut 3, between which shoulder and screw-nut the separating-ring 6 and flanges at are located. The shoulder of the hub is provided with a key-seat 2, which serves to prevent the hub from turning when the socket-wrench 6, fitted with a key 8 to enter the seat 2, is placed in position for service upon the hub. The screw-nut is also provided with a key-seat 3", (shown in Figs. 13, 14,) and when another socket-wrench 8 is placed in position for service upon the screw-nut 3 the latter may be turned sulficiently to fasten firmly the flanges 4 and the separating-ring 6 upon the hub 2.

The screw-nut 3 (shown in Figs. 1, 2 and 13, 14) is made of suitable material and keyseated at its circumference to receive a suitable socket-wrench, as 8, fitted with a key, as 8, for tightening or loosening the several details of the guide-wheel as a whole.

The flanges 4: (shown in Figs. 1, 2 and 3, i) are made of suitable material. They are each provided with a central hole, to the end that they may be duly mounted on the hub 2. They are also each provided near its circumference with straight lines, which join the curved lines 11 11 of the cavity. These straight lines of the ca'vityof the flanges are vertical or approximately vertical to the axis around which the guide-wheel revolves and serve to prevent the guide-wheel from leaving or jumping the electrical conductor or other guide when the guide-wheel is forced sidewise by jolting or otherwise. The curved lines 11 11 serve to guide the rope, wire, or the like to the center-bearing 5.

The center-bearing 5 (shown in Figs. 2 and 5, 6) is made of suitable material and pro- Vided with a central hole suitable of being mounted loosely upon the separating-ring 6 between the flanges 4, where it is capable of revolving independently of said flanges. The circumference of the center-bearing 5 is fitted with an endless groove, as indicated in Figs. 2 and 5, and the same serves as a bearing for the rope or round wire or the like, with which it may be brought in contact. At or near the circumference said center-bearing is made narrower than the diameter of such rope,wire, or the like for the purpose of reducing the difference of the different radii of which the transverse face of the center-bearing is composed, and thereby also reducing the slipping and consequent abrasion of its circumference and of the rope, wire, or the like.

The separating-ring 6 (shown in Figs. 2 and 9, 10) is made of suitable material. It is provided with acentral longitudinal hole to ad mit of its being mounted upon the hub 2 between the flanges 4-. It is made sufficiently wider than the width of the journal of the center-bearing 5 for the purpose that the latter may be able to revolve independently between the flanges, and its circumference is finished suitably to serve as a journal for said center-bearing. )Vhcn the separating-rin g (3 III) der 9" of the spider.

is placed upon the hub 2 between the flanges 4 and the screw-nut 3 is tightened, it and the flanges are held' tirmly to the hub without interfering with the independent revolution of the center-bearing.

The guide-wheel, as shown in Figs. 1 and 2, is suitable for guiding a round rope or to be guided by a round wire at its circumference. It may be used for rope transmissionsuch as cable-roads, &cor for conveying an electric current from or to an electrical conductor circular in cross-section, such as conveying current from a trolley-Wire to a motor-car.

The socket-wrench (shown in Figs. 15 and 16) is provided with a central hole, into which the hub-shoulder 2 or the screw-nut 3 is able to enter. WVithin the central hole of the wrench is fitted a key 8 to entera corresponding key-seat 2, located at the circumference of the shoulder 2, and key-seat 3, which is located at the circumference of the screw-nut It is also provided with a handle 8', which may be grasped and used as a lever when using the wrench.

The guide-wheel shown in Figs. 17, 18 and 23, 2t is designed to revolve in contact with larger rope, wire, or the like than the guidewheel shown in Figs. 1 and2. It is designed with a combined hub and spider 9. The hub is provided with a central hole to receive a shaft, around which it may revolve. It is also provided with bolt-holes 9' for bolting the flanges 10 and spider together. Shoulders 9 are provided at the side of the spider for guiding the flanges 1O accurately to place. The circumfer nce of the spider is fitted as a journal, around which the center-bearing 9 may revolve independently of the flanges 10. This guidewvheel is shown as fitted with a cylindrical center-bearing in contact with an angular wire; but the contact-face of the center-bearing may be made to fit any other form of cross-section of a wire, rope, or the like with which it is to revolve.

The flanges 10 (shown in Figs. 17, 18 and 19, 20) are each provided with a central hole, to the end that they may be fitted on the shoul- They are also provided with bolt-holes 10, which register with the bolt-holes 9' of the spider, bolts 10" being employed for fastening the flanges in place. The circumference of the flanges are provided with proper curves and straight lines 11 11 for guiding the rope, wire, or the like to the center-bearing 9.

The center-bearing 9 (shown in Figs. 17, 18 and 21, 22) is provided with a central hole for mounting it loosely upon the circumference of the spider 9 to enable it to revolve independently of the rest of the wheel. Its circumference is shown to befitted with a plain cylindrical surface as a bearing for a wire, as 12, angular in cross-section; but it may be made to fit any other form of cross-section of a wire, rope, or the like;

The guide-wheel shown in Figs. 27, 28 is another modification of the guide-wheel shown in Figs. 1, 2. It is made like an ordinary solid guide-wheel, with hub 13, spider 13', flanges wire 14. The center-bearing may be secured to the rim in any approved manner, as by screws, (indicated in Fig. 27, where'a portion of one of the flanges is broken away to show the center-bearing fastened in position for service, as by means of bolts,) or the center-bearing may be formed integral with the guide-wheel. The center-bearing shown in Fig. 28 is also made narrower at its circumference than the diameter of the rope, wire, or the like with which it is brought in contact at its circumference. The inside curves of the flanges are also shaped in such manner that they will guide the rope, wire, or the like to the center-bearing. Adjoining the .7 13", a fixed center-bearing 14, in contact with.

center-bearing are recesses 14", which permit the round rope or round wire to abrade the center-bearing some distance below its original diameter without interfering with the adjacent shoulders of the flanges. The abrasion of the circumference of the center-bearing of this guide-wheel should be limited to the extent of the rope or wire coming in contact with the shoulders of the wheel-flanges. Within thislimit this guide-wheel will effect a considerable saving inthe, expenses. incident to the renewals of the rope or wire and the guide-wheel as compared with the ordinary solid guide-wheel; but it will not beas economical as the guide-wheel fitted with the independently-revolving center-bearin g.

It will be observed that my improved guidewheel is particularly well adapted for the purpose for which it is designed and also that the same may be modified somewhat as to the details of the construction without departing from the spirit and principle of my invention.
